Camfil Farr Air Pollution Control (APC) introduces the FarrVac Junior, a pulse-cleaned industrial vacuum with dual-stage HEPA filtration. It drastically minimizes clogs, preventing the problems that result from loss of suction during cleaning using a patented pulse-cleaning technology that works without compressed air, says the manufacturer. Filters are cleaned every 10 seconds, preventing clogging. The vacuum comes equipped with spun bond polyester filters. Two primary HEPA filters provide 99.97% efficiency on dust particles to 0.3 micron. Applications include routine shop cleanup or as an accessory to an installed dust collector when replacing or emptying dust drawers or drums.
